The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0041] The embodiment of the utility model provides a packaging box cover folding mechanism, which can be used in a packaging box production line to fold the box cover of the packaging box to replace manual operation, and is particularly suitable for folding the box cover at the bottom of the packaging box. The utility model is described below through specific embodiments.

[0042] like Figure 2 As shown, a packaging box lid folding mechanism 1 includes a push plate assembly 11 and a pushing power member 12. The push plate assembly 11 includes a folding push plate 111, and the folding push plate 111 is arranged on the outside of the box lid 110. The pushing power member 12 is connected to the push plate assembly 11 and drives the push plate assembly 11 to move. The folding push plate 111 is driven by the pushing power member 12 to push the box lid 110 so that the box lid 110 is folded inward.

[0043] The box cover 110 of the packaging box 100 is pushed by the folding push plate 111 to fold it without manual intervention, especially for the folding of the box cover 110 at the bottom of the packaging box 100, there is no need to turn the box over before operation, which reduces the operation process and improves production efficiency.

[0044] The driving power member 12 may be a power member such as a cylinder or a motor 141. In this embodiment, the cylinder used is a three-axis cylinder, and the output end of the cylinder is equipped with the driving power member 12. It should be noted that the three-axis cylinder here refers to a cylinder with three push rods in the same direction. Of course, in this solution, a single-axis cylinder can also be used to replace the three-axis cylinder. The use of a single-axis cylinder requires a guide component to limit the freedom of rotation.

[0045] like Figure 2 As shown, the push plate assembly 11 further includes a limit plate 112, which is arranged at an angle with the folding push plate 111, and the opening direction of the angle formed by the limit plate 112 and the folding push plate 111 faces the packaging box 100. The limit plate 112 is connected to the output end of the driving power member 12. The main function of the limit plate 112 is to limit the packaging box 100 and prevent the packaging box 100 from rotating due to uneven force when the folding push plate 111 pushes the box cover 110.

[0046] In this embodiment, the folding push plate 111 is arranged horizontally, and the limiting plate 112 is arranged vertically. The limiting plate 112 and the folding push plate 111 form an L-shape. Such a design enables the limiting plate 112 to avoid interference with the folding push plate 111 in pushing the box cover 110 as much as possible, while ensuring that the corresponding limiting function of the limiting plate 112 can be used normally.

[0047] It should be noted that when the folding push plate 111 pushes the box cover 110, if the packaging box 100 does not rotate, the limiting plate 112 will not contact the packaging box 100. Therefore, if other means can be used to ensure that the packaging box 100 does not rotate when the folding push plate 111 pushes the box cover 110, the limiting plate 112 may not be set. This is equivalent to reducing the weight of the entire push plate assembly 11, which is more conducive to extending the service life of the pushing power member 12.

[0048] In order to further reduce the weight of the push plate assembly 11 , a plurality of hollow holes may be provided on the limiting plate 112 and / or the folding push plate 111 .

[0049] like Figure 2 The packaging box cover folding mechanism 1 also includes a lifting bracket 13, which includes a fixed plate 132, a lifting plate 131 and a sliding module 133 arranged between the fixed plate 132 and the lifting plate 131. The lifting plate 131 and the fixed plate 132 are slidably arranged through the sliding module 133, and the power member 12 is installed on the lifting plate 131.

[0050] The height of the push power member 12 can be flexibly adjusted by the provided lifting frame, and then the height of the push plate assembly 11 can be adjusted to adapt to various packaging boxes 100 of different sizes, thereby improving versatility and adaptability. At the same time, by adjusting the position of the lifting frame, it can be ensured that the folding push plate 111 applies force to the appropriate position of the box cover 110 of the packaging box 100, avoiding the problem of insufficient force application due to inappropriate height.

[0051] The sliding module 133 includes a slide rail 1331 and a slider 1332 connected to the slide rail 1331. The slide rail 1331 is vertically arranged on one of the fixed plate 132 or the lifting plate 131, and the slider 1332 is arranged on the other of the fixed plate 132 or the lifting plate 131. The cooperation between the slide rail 1331 and the slider 1332 can provide stable linear motion, ensuring that there is no shaking or offset during the lifting process, thereby improving the accuracy and consistency of the operation. In addition, the design of the slide rail 1331 and the slider 1332 can effectively reduce the friction and resistance during the lifting process, making the lifting movement smoother and avoiding sudden shaking or jamming.

[0052] like Figure 2 , 3 As shown, the packaging box cover folding mechanism 1 also includes a driving assembly 14, which includes a motor 141 and a rack 142. The output shaft of the motor 141 is in driving engagement with the rack 142. The rack 142 is vertically arranged on one of the fixed plate 132 and the lifting plate 131, and the motor 141 is arranged on the other of the fixed plate 132 and the lifting plate 131. Through the cooperation between the motor 141 and the rack 142, the rotational motion of the motor 141 is converted into the linear motion of the rack 142, thereby ensuring the accuracy and repeatability of the lifting process.

[0053] It can be understood that if the motor 141 is arranged on the lifting plate 131 and the rack 142 is arranged on the fixed plate 132, the motor 141 will move synchronously with the movement of the lifting plate 131. If the motor 141 is arranged on the fixed plate 132 and the rack 142 is arranged on the lifting plate 131, the motor 141 remains stationary on the fixed plate 132.

[0054] like Figure 3 As shown, the driving assembly 14 also includes a gear 143, the output shaft of the motor 141 is in driving engagement with the gear 143, and the rack 142 is in driving engagement with the gear 143. The number of gears 143 can be one or more, and the gear 143 and the rack 142 have the characteristics of high precision, high load bearing, and easy replacement and maintenance.

[0055] like Figure 2 As shown, two lifting brackets 13 are provided, the two lifting brackets 13 are arranged opposite to each other, and the tops of the lifting plates 131 of the two lifting brackets 13 are provided with push plate assemblies 11 and pushing power members 12, and the push plate assemblies 11 on the two lifting brackets 13 are respectively used to act on the two box covers 110 on the opposite sides of the packaging box 100.

[0056] Since there are generally two box covers 110 at the bottom of the packaging box 100 of the air conditioner indoor unit, the push plate assembly 11 of one of the two lifting brackets 13 is used to act on one of the two box covers 110, and the push plate assembly 11 of the other bracket is used to act on the other box cover 110. Such a design can realize synchronous folding operation, greatly improve the folding efficiency, and shorten the processing time of folding the box cover 110 of a single packaging box 100.

[0057] like Figure 3 As shown, a connecting plate 15 is provided between the lifting plates 131 of the two lifting brackets 13, and one of the two lifting brackets 13 is provided with a driving assembly 14. With such a design, one driving assembly 14 can be used to realize synchronous lifting of the two lifting plates 131, without setting two driving assemblies 14, which greatly reduces the cost while ensuring synchronous lifting.

[0058] The two ends of the connecting plate 15 are fixedly connected to the lower ends of the two lifting plates 131 of the two lifting brackets 13 respectively, and the connection method can be welding or connecting with connecting parts such as screws.

[0059] Since the rigidity of the connecting plate 15 directly affects the lifting accuracy of the lifting plates 131 at both ends thereof, a reinforcing plate 16 is provided at the connection between the connecting plate 15 and the lifting plate 131, and the reinforcing plate 16 is fixedly connected to the lifting plate 131 and the connecting plate 15 by bolts. The provided reinforcing plate 16 can greatly increase the strength and rigidity of the connecting plate 15.

[0060] like Figure 1 The embodiment of the utility model further provides a packaging box production line, including a water table 2, a clamp 3 and the above-mentioned packaging box cover folding mechanism 1, the clamp 3 is arranged above the water table 2, the clamp 3 is used to clamp the packaging box 100, the packaging box cover folding mechanism 1 is arranged on the side of the water table 2, the function of the water table 2 is to send the folded packaging box 100 to the next workstation, the function of the clamp 3 is to clamp the packaging box 100, the clamp 3 can be a manipulator or other types of automated clamping equipment, and the spatial movement of the clamp 3 can be achieved by a robot or a three-axis module.

[0061] In this embodiment, the left and right sides of the water flow table 2 (with Figure 1 The lower ends of the lifting plates 131 on the left and right sides are connected by a connecting plate 15 that crosses the bottom of the water table 2. The packaging box 100 is clamped to the top of the water table 2 by the clamp 3, and the packaging box 100 is stopped at a predetermined height. The box cover 110 at the bottom of the packaging box 100 is pushed by the folding push plate 111 to fold it.

[0062] Through the cooperation between the water table 2, the clamp 3 and the above-mentioned packaging box cover folding mechanism 1, the entire folding process can be fully automated, reducing manual intervention and improving the automation level of the production line. At the same time, the water table 2 can continuously send the folded packaging box 100 to the next station, realizing automated assembly line operation and greatly improving production efficiency.

[0063] After the box cover 110 at the bottom of the packaging box 100 of the air conditioner indoor unit is folded using the structure of the utility model, 400 air conditioner indoor units can be folded per hour, while the previous manual operation can only complete 250 units. Therefore, the automatic equipment of the utility model can increase the output by at least 50%, thereby shortening the production cycle. Only the control mechanism needs to be operated to complete the automatic operation, without complicated manual operation, and without facing the safety hazards caused by manual operation.

[0064] like Figure 1-Figure 9 As shown, the embodiment of the utility model further provides a box cover 110 folding method of a packaging box production line, and the method includes the following steps: S10-S40.

[0065] S10 , the clamp 3 clamps the packaging box 100 and moves to a predetermined height position above the water flow table 2 .

[0066] The clamp 3 moves the packaging box 100 to the top of the water table 2 and lifts it to a predetermined height position, which is pre-set to ensure that the subsequent folding operation can proceed smoothly.

[0067] S20, using the push plate assembly 11 to push the box cover 110 at the bottom of the packaging box 100, so that the box cover 110 at the bottom of the packaging box 100 is folded inward at a certain angle.

[0068] The folding push plate 111 of the push plate assembly 11 is pushed out horizontally under the driving force of the driving power member 12, and the box cover 110 in the vertical state is folded inward under the horizontal thrust, and the folding angle can be 20 degrees or 30 degrees. It should be noted that the folding angle only needs to meet the condition that the box cover 110 can automatically fold inward to a horizontal state under the contact with the table 21 of the water table during the process of placing the packaging box 100 on the water table 2.

[0069] S30 , after the box cover 110 at the bottom of the packaging box 100 is folded inwards at a certain angle, the clamp 3 clamps the packaging box 100 and descends together with the push plate assembly 11 .

[0070] The clamp 3 continues to clamp the packaging box 100 and moves in coordination with the push plate assembly 11 to descend as a whole. The process of descending is to make the box cover 110 at the bottom of the packaging box 100 gradually approach the table 21 of the water table.

[0071] S40, when the box cover 110 at the bottom of the packaging box 100 contacts the table surface 21 of the water flow table, the clamp 3 is released and separated from the packaging box 100, and the push plate assembly 11 is reset.

[0072] When the box cover 110 at the bottom of the packaging box 100 contacts the table 21 of the water table, and the clamp 3 is released and separated from the packaging box 100, the box cover 110 will automatically fold inwards under its own gravity until it is folded into a horizontal state, thus completing the entire folding process. After the folding action is completed, the clamp 3 and the push plate assembly 11 are reset to the initial position to prepare for the next operation.

[0073] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
